He felt little sense of urgency, none of responsibility. He was a diplomat,'not a Friend, as the spies were called. And Friends in Palmer's zoology were people without the - 45 intellectual horsepower to be what Palmer was, Indeed it was his outspoken resentment that the orthodox Foreign Office to which he belonged resembled more and more a cover organisation for the Friends' disgraceful activities. For Palmer too was a man of impressive erudition, if of a random kind. He had read Arabic and taken a First in Modem History. He had added Russian and Sanskrit in his spare time. He had everything but mathematics and common sense, which explains why he passed over the dreary Pages of algebraic formulae, equations and diagrams that made up the other two notebooks, and in contrast to the writer's philosophical ramblings had a boringly disciplined appearance. And which also explains - though the committee had difficulty accepting such an explanation - why Palmer chose to ignore the Standing Order to Resident Clerks relating to Defectors and Offers of Intelligence whether solicited or otherwise, and to do his own thing.

'He makes the most frantic connections right across the board, Tig,' he told a rather senior colleague in Research Department on the Tuesday, having decided,that it was finally time to share his acquisition. 'You simply must read him.'

'But how do we know it's a he, Palms?'

Palmer just felt it, Tig. The vibes.

Palmer's senior colleague glanced at the first notebook, then at the second, then sat down and stared at the third. Then he looked at the drawings in the second book. Then his professional self took over in the emergency.

'I think I'd get this lot across to them fairly sharpish if I were you, Palms,' he said. But on second thoughts he got it across,to them himself, very sharpish indeed, having first telephoned Ned on the green line and told him to stand by.

Upon which, two days late, hell broke loose. At four o'clock on the Wednesday morning the lights on the top floor of Ned's stubby brick out-station in Victoria known as the Russia House were still burning brightly as the first bemused meeting of what later became the Bluebird team drew to a close. Five hours after that, having sat out two more meetings in the Service's headquarters in a grand new high-rise block on the Embankment. Ned was back at his desk, the files gathering around him as giddily as if the girls in Registry had decided to erect a street barricade.

'God may move in a mysterious way,' Ned was heard to remark to his red-headed assistant Brock in a lull between deliveries, 'but it's nothing to the way He picks his joes.'

A joe in the parlance is a live source, and a live source in sane English is a spy. Was Ned referring to Landau when he spoke of joes? To Katya? To the unchristened writer of the notebooks? Or was his mind already fixed upon the vaporous outlines of that great British gentleman spy, Mr. Bartholomew Scott Blair? Brock did not know or care. He came from Glasgow but of Lithuanian parents and abstract concepts made him angry.

As to myself, I had to wait another week before Ned decided with a proper reluctance that it was time to haul in old Palfrey. I've been old Palfrey since I can remember. To this day I have never understood what happened to my Christian names. 'Where's old Palfrey?' they say. 'Where's our tame ' legal eagle? Get the old law bender in! Better chuck this one at Palfrey!'

I am quickly dealt with. You need not stumble on me long. Horatio Benedict dePalfrey are My names but you may forget the first two immediately, and somehow no body has ever remembered the 'dc' at all. In the Service I am Harry so, quite often, being an obedient soul, I am Harry to myself, Alone in my poky little bachelor flat of an evening, I am quite inclined to call myself ' Harry while I cook my chop. Legal adviser to the illegals, that's me, and sometime junior partner to the extinct house of Mackie, Mackie & dePalfrey, Solicitors and Commissioners for Oaths, of Chancery Lane. But that was twenty years ago. For twenty years I have been your most humble secret servant, ready at any time to rob the scales of the same blind goddess whom my young heart was brought up to revere.

A palfrey, I am told, was neither a warhorse nor a hunter, but a saddle horse deemed suitable for ladies. Well, there's only one little lady who ever rode this Palfrey any distance, but she rode him nearly to his grave and her name was Hannah. And it was because of Hannah that I scurried for shelter inside the secret citadel where passion has no place, where the walls are so thick I cannot hear her beating fists or tearful voice imploring me to let her in and brave the scandal that so terrified a young solicitor at the threshold of a respectable career.

Hope in my face and nothing-in my heart, she said. A wiser woman might have kept such observations to herself, it has always seemed to me. Sometimes the truth is by way of being a self-indulgence. 'Then why do you pursue a hopeless case?' I would protest to her. 'If the patient is dead, why keep trying to revive him?'

Because she was a woman, seemed to be the answer. Because she believed in the redemption of male souls. Because I had not paid enough for being inadequate.

But I have paid now, believe me.

It is because of Hannah that I walk the secret corridors to this day, calling my cowardice duty and my weakness sacrifice. It is because of Hannah that I sit here late at night, in my grey box of an office with LEGAL on the door, files and tapes and films stacked around me like the case of Jarndyce v. Jarndyce without the pink string, while I draft our official whitewash,of the operation we called the Bluebird and of its protagonist, Bartholomew, alias Barley, Scott Blair.

It is because of Hannah also that even while he scribbles at his exculpation this old Palfrey now and then puts down his pen and lifts his head and dreams.

Niki Landau's recall to the British colours, if he had ever seriously abandoned them, took place exactly forty-eight hours after the notebooks hit Ned's desk. Ever since his miserable passage through Whitehall, Landau had been sick with anger and mortification. He hadn't gone to work, he hadn't bothered with his little flat in Golders Green which he normally buffed and pampered as if it were the lantern of his life. Not even Lydia could rouse him from his melancholy. I myself had hastily arranged the Home Office warrant to tap his phone. When she telephoned, wit listened to him putting her off. And-when she made a tragic appearance at his front door, our watchers reported that he let her stay for a cup of tea and then dismissed her.

'I don't know what I've done wrong but whatever it is, I'm sorry,' they heard her remark sadly as she left.

She was hardly in the street before Ned rang. Afterwards Landau shrewdly wondered to me whether that was a coincidence.

'Niki Landau?' Ned enquired in a voice you didn't feel like fooling with.

'I could be,' said Landau, sitting up straight.

'My name's Ned. I think we have a mutual friend. No need to mention names. You kindly dropped a letter in for him the other day. Rather against the odds, I'm afraid. A package too.'

Landau thrilled to the voice immediately. Capable and commanding. The voice of a good officer, not a cynic, Harry.

'Well, yes, I did,' he said, but Ned was already talking again.

'I don't think we need to go into a lot of details over the telephone, but I do think you and I need to have a long chat and I think we need to shake your hand. Rather soon. When can we do that?'

'Whenever you say,' said Landau. And had to stop himself from saying 'sir'.

'I always think now's a good time. How do you feel about that?'

'I feel a whole lot better, Ned,' said Landau with a grin in his, voice.

'I'm going to send a car for you. Won't be at all long, so perhaps you'd just stay where you are and wait for your front doorbell to ring. It's a green Rover, B registration. The driver's name is Sam. If you're worried, ask him to show you his card. If you're still worried, phone the number on it. Think you'll manage?'

'Our friend's all right, is he?' said Landau, unable to resist asking, but Ned had rung off.

The doorbell pealed a couple of minutes afterwards. They had the car waiting round the corner, thought Landau as he floated downstairs in a dream. This is it. I'm in the hands of the professionals. The house was in smart Belgravia, one of a terrace recently restored. Its newly painted white front glistened wholesomely at him in the evening sun. A palace of excellence, a shrine to the secret powers that rule our lives. A polished- brass sign on the pillared doorway said FOREIGN LIAISON STAFF. The door was already opening as Landau climbed the steps. And as the uniformed janitor closed it behind him Landau saw a slender, straight-built man in his early forties advance towards 'him through the sunbeams, first the trim silhouette, then the no-nonsense handsome healthy features, then the hand shake: discreet but loyal as a naval salute.

'Well done, Niki. Come on in.'

Good voices do not always belong to good faces, but Ned's did. As Landau followed him into the oval study, he felt he could say anything in the world to him, and Ned would still be on his side. Landau in fact saw a whole lot of things in Ned that he liked at once, which was Ned's Pied Piper gift: the careful charm, the restrained good looks, the power of ' quiet leadership and the 'Come on in.' Landau also sniffed the polyglot in him, for he was one himself. He had only to drop a Russian name or phrase for Ned to reach out for it and smile, and match it with a phrase of his own. He was one of us, Harry. If you had a secret, this was the man to tell it to, not that flunkey in the Foreign Office.

But then Landau had not realised, until he began talking, hi;w desperately he had been needing to confide. He opened his mouth, he was away. All he could do from then on was listen to himself in amazement, because he wasn't just talking about Katya and the notebooks, and why he had accepted them, and how he had hidden them, but about his whole life till now, his confusions about being a Slav, his love of Russia despite everything, and his feeling of being suspended between two cultures. Yet Ned did not lead him or check him in any way. He was a born listener. He hardly stirred except to write himself neat notes on bits of card, and if he interrupted, it was only to clear up a rare point of detail - the moment at Sheremetyevo, for example, when Landau was waved through to the departure lounge without a glance.

'Now did all your group receive that treatment or only you?'

'The lot of us. One nod, we were through.'

'You didn't feel singled out in any way?'
